In order to keep the tables as small as possible, I'm making each segment of base and fused separate, so here is the list of boosters that were once Rares that I've already turned into SR+ cards. Probably will end up being a relatively short list compared to the others.
As these are the fused forms, I will include a third column for skill level as it may be good to know.
